How does anti-colic system work?
Air enters from the vent adapter and routes directly through the internal vent system. Air passes through the vent tube, bypassing the milk, to the end of the bottle. Air does not dissolve into the milk. The anti-colic system balances the internal and external air pressure. The baby can be fed continuosly without swallowing air.
